D4.2 Drum editor does not display icons for rhythmic grid per kit piece

I am loving the new drum kit editor. This is a big step forward, especially considering it is part of a free update. In viewing Anthony’s video, it shows a small note icon on each kit piece:

The idea is you can click on that icon to set the rhythmic grid differently for different kit pieces. For example, you might want the kick to be quarter notes or eighth notes, but you might want the hi-hat to be 16th notes…

Those icons are not showing up on my Windows 10 system.

Is there something I have to do to enable them?

Answering my own question, those icons appear only when you select the mallet tool, which makes sense.
